Its easy-to-maintain design can be installed quickly and easily to minimize maintenance times. Sustained release provides long-lasting fragrancing to keep restrooms smelling great for at least 30 days. Plus, the on-trend fragrance can be matched with other ActiveAire supplies to keep a consistent experience in restrooms. Passive freshener refill is designed for use with Georgia-Pacific ActiveAire Whole-Room Freshener Dispensers (sold separately).
